[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The following describes a filled friction pendulum seismic isolation bearing 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0031] like Figure 1-Figure 7 As shown, the filled friction pendulum isolation bearing 1 according to the embodiment of the present invention includes an upper bearing plate 100, a lower bearing plate 200 and a slider 300 (the up and down directions are shown by the arrows in the figure and are only for the convenience of expression, not for limiting the actual setting direction).

[0032] The lower surface of the upper support plate 100 has an upper sliding friction surface 101, and an upper filling cavity 102 is provided in the upper support plate 100. The upper surface of the lower support plate 200 has a lower sliding friction surface 201, and a lower filling cavity 202 is provided in the lower support plate 200, and the upper filling cavity 102 and the lower filling cavity 202 are filled with a filling material 400. The upper surface of the slider 300 has an upper sliding layer 310 and the lower surface has a lower sliding layer 320, the upper sliding friction surface 101 and the upper sliding layer 310 are slidably matched to make the slider 300 slide relative to the upper support plate 100, and the lower sliding friction surface 201 and the lower sliding layer 320 are slidably matched to make the slider 300 slide relative to the lower support plate 200.

[0033] It can be understood by those skilled in the art that when the filled friction pendulum seismic isolation bearing 1 is applied to a construction project, the upper bearing plate 100 is connected to the upper structure of the building, and the lower bearing plate 200 is connected to the lower structure or foundation of the building.

[0034] According to the filled friction pendulum seismic isolation bearing 1 of the embodiment of the present invention, by providing an upper sliding friction surface 101, a lower sliding friction surface 201, an upper sliding layer 310 and a lower sliding layer 320, the relative sliding of the bearing plate and the sliding block 300 can be achieved through the sliding cooperation of the sliding friction surface and the sliding layer. When subjected to horizontal vibration, the sliding cooperation of the sliding friction surface and the sliding layer eliminates the horizontal vibration to achieve horizontal vibration isolation, so that the filled friction pendulum seismic isolation bearing 1 forms a vibration isolation layer with smaller horizontal stiffness in the building, thereby reducing the response of the horizontal vibration of the ground in the upper structure.

[0035] Furthermore, by respectively providing an upper filling cavity 102 and a lower filling cavity 202 in the upper support plate 100 and the lower support plate 200, compared with the support plates made of solid steel in the related art, on the one hand, the material cost of the upper support plate 100 and the lower support plate 200 can be reduced, and the weight of the upper support plate 100 and the lower support plate 200 can be reduced, thereby facilitating the transportation and installation of the upper support plate 100 and the lower support plate 200; on the other hand, compared with cutting solid steel, the processing difficulty and processing cost of the upper support plate 100 and the lower support plate 200 can be reduced.

[0036] In addition, by setting the filling material 400, the upper filling cavity 102 and the lower filling cavity 202 can be filled with the filling material 400, so that the hollow part in the support plate can be filled with the filling material 400, and the filling material 400 can be used to support the shape of the upper support plate 100 and the lower support plate 200, thereby ensuring the structural strength and stability of the upper support plate 100 and the lower support plate 200, so that the upper support plate 100 and the lower support plate 200 have a structural strength close to that of solid steel.

[0037] Therefore, the filled friction pendulum seismic isolation bearing 1 according to the embodiment of the present invention has the advantages of low processing difficulty, convenient transportation and installation, and low cost.

[0038] The following describes a filled friction pendulum seismic isolation bearing 1 according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0039] In some specific embodiments of the present invention, Figure 1-Figure 7 As shown, the filled friction pendulum seismic isolation bearing 1 according to the embodiment of the present invention includes an upper bearing plate 100 , a lower bearing plate 200 and a sliding block 300 .

[0040] Optionally, the upper support plate 100 and the lower support plate 200 are metal parts, and the filling material 400 is concrete. Specifically, the upper support plate 100 and the lower support plate 200 can be steel parts, and carbon structural steel, alloy structural steel, stainless steel or composite steel parts are preferred. The concrete is an engineering composite material that uses cement as a cementitious material to bond aggregates such as sand, stone, and recycled aggregate into a whole. The filling material 400 can also use fiber-reinforced concrete, and its performance is adjusted by adding fibers to the concrete material. In addition to the concrete material widely used in engineering, plastic can also be used as the filling material 400 to achieve a very small component weight, or aluminum casting can be used to take into account weight, strength and durability. This can facilitate the processing and molding of the upper sliding friction surface 101 and the lower sliding friction surface 201, and facilitate the filling of the filling material 400.

[0041] Specifically, Figure 1 , Figure 4-Figure 6 As shown, the upper sliding friction surface 101 and the lower sliding friction surface 201 are concave spherical surfaces, the upper sliding layer 310 and the lower sliding layer 320 are convex spherical surfaces, the upper sliding friction surface 101 has the same curvature as the upper sliding layer 310, and the lower sliding friction surface 201 has the same curvature as the lower sliding layer 320. This makes it easier for the sliding friction surface and the sliding layer to slidably cooperate to achieve seismic isolation against horizontal earthquakes.

[0042] More specifically, Figure 4 and Figure 5As shown, the upper support plate 100 includes an upper connecting plate 110, an upper enclosure plate 120 and an upper spherical panel 130. The upper end of the upper enclosure plate 120 is connected to the upper connecting plate 110. The upper spherical panel 130 is connected to the lower end of the upper enclosure plate 120. The upper connecting plate 110, the upper enclosure plate 120 and the upper spherical panel 130 jointly define an upper filling cavity 102, and an upper sliding friction surface 101 is formed on the lower surface of the upper spherical panel 130. In this way, when processing the upper sliding friction surface 101, only the plate of the upper spherical panel 130 needs to be processed. Compared with the method of integrally processing the support plate of solid steel in the related art, the split processing of the upper support plate 100 can be facilitated, thereby further reducing the manufacturing difficulty and manufacturing cost of the upper support plate 100.

[0043] Advantageously, if Figure 4 As shown, the upper ball panel 130 includes an upper ball panel body 131 and an upper sliding panel 132. The upper ball panel body 131 is connected to the lower end of the upper enclosure 120. The upper sliding panel 132 is detachably arranged on the lower surface of the upper ball panel body 131, and the upper sliding friction surface 101 is formed on the lower surface of the upper sliding panel 132. In this way, the upper sliding panel 132 can be disassembled, which is convenient for repairing and replacing the upper sliding panel 132 and for maintaining the upper sliding friction surface 101.

[0044] In some embodiments of the present invention, Figure 1 As shown, the lower support plate 200 includes a lower connecting plate 210, a lower enclosure plate 220 and a lower ball panel 230. The lower end of the lower enclosure plate 220 is connected to the lower connecting plate 210. The lower ball panel 230 is connected to the upper end of the lower enclosure plate 220. The lower connecting plate 210, the lower enclosure plate 220 and the lower ball panel 230 jointly define a lower filling cavity 202. The lower sliding friction surface 201 is formed on the lower surface of the lower ball panel 230. The curvature of the lower sliding friction surface 201 is the same as that of the upper sliding friction surface 101. In this way, when processing the lower sliding friction surface 201, only the plate of the lower ball panel 230 needs to be processed. Compared with the method of integrally processing the support plate of solid steel in the related art, the split processing of the lower support plate 200 can be facilitated, thereby further reducing the manufacturing difficulty and manufacturing cost of the lower support plate 200.

[0045] Specifically, Figure 1 As shown, the lower ball panel 230 includes a lower ball panel body 231 and a lower sliding panel 232. The lower ball panel body 231 is connected to the upper end of the lower enclosure 220. The lower sliding panel 232 is detachably arranged on the upper surface of the lower ball panel body 231, and the lower sliding friction surface 201 is formed on the upper surface of the lower sliding panel 232. In this way, the lower sliding panel 232 can be disassembled, which is convenient for repairing and replacing the lower sliding panel 232 and for maintaining the lower sliding friction surface 201.

[0046] It is understood by those skilled in the art that the lower support plate 200 and the upper support plate 100 may adopt the same structure but only be arranged in opposite directions, which can simplify the types of parts and facilitate the manufacture of the filled friction pendulum seismic isolation support 1.

[0047] In other embodiments of the present invention, Figure 6 and Figure 7 As shown, the lower support plate 200 includes a lower connecting plate 210, a lower enclosure plate 220, a lower cover plate 240 and a lower sliding end portion 250. The lower end of the lower enclosure plate 220 is connected to the lower connecting plate 210. The lower cover plate 240 is connected to the upper end of the lower enclosure plate 220. The lower sliding end portion 250 is connected to the lower cover plate 240, the diameter of the lower sliding end portion 250 is smaller than the diameter of the lower cover plate 240, the lower end of the lower sliding end portion 250 is lower than the lower surface of the lower cover plate 240, the lower connecting plate 210, the lower enclosure plate 220, the lower cover plate 240 and the lower sliding end portion 250 jointly define a lower filling cavity 202, the lower sliding friction surface 201 is formed on the upper surface of the lower sliding end portion 250, and the curvature of the lower sliding friction surface 201 is greater than the curvature of the upper sliding friction surface 101. In this way, the relative sliding range between the lower sliding end 250 and the slider 300 can be reduced, and a drastic change in the load position of the slider 300 on the lower support plate 200 can be avoided. This is suitable for building structures with higher requirements for lower stability.

[0048] Specifically, the upper ball panel body 131 and the upper sliding panel 132 can be detachably connected by a threaded fastener 600, and the lower ball panel body 231 and the lower sliding panel 232 can be detachably connected by a threaded fastener 600, and the threaded fastener 600 can be a screw or a bolt. The lower end surface of the upper enclosure 120 can be provided with an avoidance groove 610, and the bottom wall of the avoidance groove 610 can be provided with a threaded hole 620, and the threaded fastener 600 is matched in the threaded hole 620. This can facilitate the connection and installation of the ball panel body and the sliding panel.

[0049] It will be understood by those skilled in the art that different steel materials may be used for the various components of the upper support plate 100 and the various components of the lower support plate 200, respectively, so as to further reduce the cost of the filled-type friction pendulum seismic isolation bearing 1 while ensuring the structural strength and vibration reduction effect of the filled-type friction pendulum seismic isolation bearing 1.

[0050] Specifically, the upper connecting plate 110 is used to connect to the upper structure of the building, and the lower connecting plate 210 is used to connect to the lower structure or foundation of the building. The upper connecting plate 110 and the lower connecting plate 210 are both provided with connecting holes 500 for connecting to other structures. This makes it easy to connect the filled friction pendulum seismic isolation bearing 1 to other structures of the building.

[0051] Specifically, Figure 1-Figure 7As shown, the upper surface of the upper bearing plate 100 and the lower surface of the lower bearing plate 200 are both provided with casting holes 410 and vent holes 420, and the inner top surface and inner bottom surface of the upper filling cavity 102 and the inner top surface and inner bottom surface of the lower filling cavity 202 are both provided with studs 430. The casting holes 410 can facilitate the pouring of concrete in the filling cavity, the vent holes 420 can facilitate the discharge of air in the filling cavity, and the studs 430 can transfer the force of the bearing plate to the concrete, so that the concrete and the support seat can be coordinated to bear the force, thereby improving the stability and reliability of the filled friction pendulum seismic isolation bearing 1.

[0052] In some embodiments, the slider 300 is a solid metal piece, which can improve the structural strength of the slider 300.

[0053] In some other embodiments, the slider 300 has a slider filling cavity therein, and the slider filling cavity is filled with a filling material 400. This can reduce the weight of the slider 300 and reduce the difficulty of processing the slider 300.

[0054] In some further embodiments, the slider 300 is an elastic member, so that the filled friction pendulum seismic isolation bearing 1 can be applied to certain scenarios requiring specific vertical stiffness.

[0055] Other structures and operations of the filled friction pendulum isolation bearing 1 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
